开发的变形监测与分析系统软件，可以在施工过程中以及工程运营期间对整个工程进行变形监测处理，用以确定基础沉降和桩顶变形以及轨道梁平面位置的变化，从而可以为以后的同类工程建设提供依据。

But it is easily noticed that certain activities, such as the maintainance and reengineering of the software, the modernization of the code written before, remain problems unsolved in this field. The solution of these problems largely depends on the programm-intepretaion, namely, to reconstruct the demain model and to document with new characteristics through the analyzation (black- or white-box, static or dynamic) of the old code by using advanced tools.

但我们也能很容易的发现软件维护、遗留代码的现代化改造以及软件的再工程问题等都是软件界普遍关注的话题，以上这些问题的有效解决很大程度上依赖于程序理解，即利用现代化分析工具或者转化系统对遗留代码进行白盒/黑盒、动态或者是静态分析，提取信息，获取抽象描述，从而达到重构具有现代意识的各类文档和领域模型。

The study found that free-stage has no effect on performance, to be end as soon as possible; the pressure and oil-filling time in oil-filled stage are the key, which directly determines the speediness of the starting; slipping-stage decides the comfort of the starting, and the friction coefficient is important for this stage, synchronous engaging-stage don't product slipping loss, and don't impact the jerk of the vehicle, needing to be finished fast. According to control object and evaluate guidelines, the fuzzy control algorithm is developed and different experiments verify the correction of algorithm.5 With the debug of CVT control software, the experiment is finished in two years which includes test bench experiment, 60℃high temperature test in Tulufan of Sinkiang province, 4647 meters high altitude test at Kunlun mountains, as well as the minimum temperature of -32℃test at Heihe.
